Cory earns $20 for every lawn he mows and $9 for every hedge he trims. he uses the expression 20x + 9y to keep track of his earnings. part a: identify the coefficients and variables in the expression. part b: how many terms are in the expression, what are they, and how do you know? part c: which term in the expression shows the total earned from trimming hedges? .

i believe the answer is c.

a) at most means it can cost $12 or less

so the inequality sign would be ≤

you would then need to multiply the number of toppings by the 0.35 for each one and add it to the cost of the cheese pizza.

the equation would be 9.99 + 0.35x ≤ 12

b) using the above equation:

9.99 + 0.35x ≤ 12

subtract 9.99 from each side:

0.35x ≤2.01

divide both sides by 0.35:

x ≤ 2.01 / 0.35

x ≤5.74

at most you could have 5 toppings.

the 5 topping pizza would cost: 0.35 x 5 = 1.75 + 9.99 = $11.74
